  • System and method for access point based positioning
    Patent number: 8924155
    Abstract: Apparatus and methods for scanning for access points (APs) for wireless local area network (WLAN) positioning. In one embodiment a wireless device includes a WLAN positioning system. The WLAN positioning system includes an AP scanner. The AP scanner is configured to determine which WLAN channels are being used by APs proximate to the wireless device. The AP scanner is also configured to scan for AP transmissions only the WLAN channels determined to be used by APs proximate to the wireless device. The AP scanner is further configured to extract signal strength and AP identification information for WLAN positioning from the AP transmissions on the scanned channels.

  • Vehicle navigation system with dead reckoning
    Patent number: 8825397
    Abstract: A vehicle navigation system includes a GNSS position engine (GPE) that uses GNSS satellite measurements to compute a first position and velocity of a vehicle and a first quality metric associated with the position and velocity. The system also includes a dead reckoning engine (DRE) that operates parallel with the GPE that computes a second position and velocity and a second quality metric associated with the dead reckoning. The GPE is configured to use the second position and velocity to detect a set of outliers in an incoming GNSS measurement; use the second position and velocity as an initial estimate of its position and velocity for a particular time instant, which is then refined by GNSS measurements received at that particular time instant; and to replace the first position and velocity with the second position and velocity.
